D., Vice President for Research and Graduate Studies and Dean of the Graduate College August 2011 ii ABSTRACT Comparison of Design-Build and Design-Bid-Build Performance of Public University Projects By James David Fernane Dr. Pramen P. Shrestha, Examination Committee Chair Assistant Professor University of Nevada, Las Vegas With an unsure market and scarce work, owners across the United States, especially universities, are finding themselves in situations where they are unable to complete their projects within cost and schedule using the traditional delivery method: Design–Bid– Build (DBB). Under the DBB project delivery method, many competent contractors are electing to send low bids on projects just to keep work on their books, with plans to receive change orders once the project is underway; this practice is leading to cost and schedule overruns. Public universities across the United States are beginning to elect to use Design-Build (DB) as an alternate project delivery method over the traditional project delivery method of DBB in order to aid in reducing the cost, schedule, and change orders. Due to current legislation in effect, all 50 states are able to use the DB delivery method. However, only 20 states and their public agencies are permitted to use DB for all types of design and construction projects. In 18 states, DB is widely permitted, but not all agencies are permitted to use this delivery method. In the remaining 12 states, DB is a limited option. iii In order to analyze and compare Design-Build (DB) and Design-Bid-Build (DBB) projects, this study collected data, by means of convenient random sampling, from construction projects built by Planning and Construction Departments of U.S. universities. Statistical tests were conducted to determine if the metrics related to cost, schedule, and change orders were significantly different from each other in these two types of projects. The findings of this study will help public universities decide what delivery method is best for them in terms of controlling costs, schedule, and change orders. The results showed that DB projects significantly outperformed DBB projects in terms of Contract Award Cost Growth, Design and Construction Schedule Growth, Total Schedule Growth, Construction Intensity, Construction Change Order Cost Growth, and Total Change Order Cost Growth. iv ACKNOWLEDGEMENTS I would like to take this opportunity to thank those individuals who made this research project possible.

  • Building Civil Engineer 7244
    11-16-90 BUILDING CIVIL ENGINEER, 7244 Summary of Duties: A Building Civil Engineer plans, organizes, and directs the work of an engineering group checking plans, designs and specifications for a variety of buildings for compliance with the Los Angeles City Building Code, Planning and Zoning Code, and the State Building Codes for energy conservation and building access by the physically disabled. A Building Civil Engineer performs professional civil engineering work when checking plans for the more complex buildings and making special engineering studies. Incumbents use sound supervisory rules and techniques to build and maintain an effective staff and satisfy affirmative action responsibilities, and does related work. Distinguishing Features: A Building Civil Engineer normally supervises an engineering group which checks plans, designs, and specifications for structural as well as non-structural criteria on a variety of buildings. A Building Civil Engineer personally directs or performs the more difficult work or has overall responsibility for a project and uses considerable independent judgment in carrying it out. A Building Civil Engineer determines what is to be done, personally supervises the most difficult parts of the work, and delegates work to subordinates. As a bona fide supervisor, a Building Civil Engineer performs the full range of supervisory activities including: disciplining employees, taking care of grievances, rating employee performance, and approving time-off requests. The classes of Building Civil Engineer and Civil Engineer are different because: * A Civil Engineer supervises employees preparing plans, designs, and specifications for bridges, sewage treatment plants, and other public construction projects. * A Building Civil Engineer supervises employees checking structural, civil, and architectural plans to enforce the building, planning and zoning, energy, grading, and handicapped codes and regulations for private as well as public construction.

On the Monetary Impact of Fashion Design Piracy Abstract Whether to legally protect original fashion designs against design piracy (“knockoffs”) is an ongoing debate among legislators, industry groups, and legal academic circles, yet to-date this discussion has not utilized marketing knowledge and formal approaches. We combine data collected on the growth of fashion items, price markups, and industry statistics, to create a formal analysis of the essential questions in the base of the debate. We distinguish between three effects: Acceleration, whereby the presence of a pirated design increases the awareness of the design, and thus might have a positive effect on the growth of the original; Substitution, which represents the loss of sales due to consumers who would have purchased the original design, yet instead buy the knockoff; and the loss due to Overexposure of the design that follows the loss of uniqueness due to the design becoming too popular, causing some consumer not to adopt the design or stop using it.

Interior design is the essence of the interior space design, including physical space design and psychological space design two levels. Interior design style is an important issue for interior designers and owners. Through analysis and Research on the relationships between design and interior design style of interior space, summed up the "interior space design to create a style of interior design" and "interior design style shape the psychological space two obvious characteristics. Interior Space Design and Its Content The Meaning of Interior Space Design. Interior space design is a creative activity of human transformation of living space, through the interior space design can make human living environment become more comfortable [1]. Although the "interior space design" theory is not a long time, but has been constantly being human practice. Since ancient times, human beings have been in the pursuit of the security of living space. Full, comfortable and beautiful. People in the primitive society in the cave laying leaves, weeds and skins and in the walls of the cave with color drawing lines and patterns, and so on for living space transformation, which all belong to the indoor space design. Interior space design is not only focused on solving the relationship between people and nature, but also more and more focus on solving the problem of the relationship between people and society, so that people in the community better work and life.

  • An Estimable Resource in the Actual Crisis of Civil Engineering?

Dragados, 2003. History of construction: An estimable resource in the actual crisis of civil engineering? Wemer Lorenz RISE AND DECLINE -A FIVE-MINUTE HISTORY OF THE CIVIL ENGINEER In the year 1762, the librarian of the Roman cardinal Albani, Johann Joachim Winckelmann, born in the North German town of Stendal, published a pamphlet titled «Anmerkungen über die Baukunst der alten Tempel zu Girgenti in Sizilien» (Remarks on the Architecture of the 01d Temples at Girgenti in Sicily) (Winckelmann 1762). In no time, this publication became the manifesto of the young neo-c1assicist movement in Europe. Evaluating his own systematic research of antique architecture, Winckelmann ca11s it the most appropriate model for any form of architecture, inc1uding contemporary. He distinguishes c1early between the «Wesentliche» (essential) and the «ZierJichkeit in der Baukunst» (daintiness of architecture). The c1ear distinction signifies an abrupt turning away from the previous baroque perception of architecture. The concept of the «essential» introduces construction as a defining parameter into architectural theory. According to Winckelmann architecture results primarily from constructive considerations. Noteworthy also is the context of his publication. Only a few years prior, in an Italian publication from 1748, one can find the term «inginiero civile» and in 1768, the term civil engineer is used for the first time in England, where the first «Society of Civil Engineers of the Kingdom» is founded in 1771. The Figure 1 civil engineer is born.

  • Change Orders Ordeal: the Output of Project Disintegration
    International Journal of Business, Humanities and Technology Vol. 2 No. 1; January 2012 Change Orders Ordeal: The Output of Project Disintegration Roberto Soares, Ph.D., D.Sc., AIC, PE Assistant Professor College of Computing, Engineering and Construction University of North Florida Jacksonville, Florida United States of America Abstract Change orders are one of the most controversial issues in construction contracts and require successful negotiations to avoid claims and possible litigation. Contractors, owners and architects behave differently when dealing with change orders. The aim of this paper is to demonstrate that change orders are the natural result of the disintegration of design and construction, which started in the US in 1893 with a Congressional Act formally separating the design and construction phases of a capital project .Delivery methods such as Design-Build (DB) and Construction Management at Risk (CMR), which are designed to mend the missing integration of design and construction and, consequently, eliminate the existence of change order conflict are proposed to recover the level of integration that existed at the time of the master builder. Key words: change orders, project integration, design-build, delivery methods 1. Introduction Change orders in construction are one of the most controversial issues to manage and a challenge to project management to satisfactorily resolve any change in order to avoid claims. Any construction contract is signed under the principle of “good faith,” which means that the parties will trust each other to perform according to the contract and that the contract is fair with no intention of taking advantage of the parties during the life of the contract.

  • Meaningful Urban Design: Teleological/Catalytic/Relevant
    Journal ofUrban Design,Vol. 7, No. 1, 35– 58, 2002 Meaningful Urban Design: Teleological/Catalytic/Relevant ASEEM INAM ABSTRACT Thepaper begins with a critique ofcontemporary urban design:the eldof urban designis vague because it isan ambiguousamalgam of several disciplines, includingarchitecture, landscapearchitecture, urban planningand civil engineering; it issuper cial because itisobsessedwith impressions and aesthetics ofphysical form; and it ispractised as an extensionof architecture, whichoften impliesan exaggerated emphasison theend product. The paper then proposesa meaningful(i.e. truly consequential to improvedquality of life) approach to urban design,which consists of: beingteleological (i.e. driven by purposes rather than de ned by conventional disci- plines);being catalytic (i.e. generating or contributing to long-term socio-economic developmentprocesses); andbeing relevant (i.e. grounded in rst causes andpertinent humanvalues). The argument isillustratedwith a number ofcase studiesof exemplary urban designers,such asMichael Pyatok and Henri Ciriani,and urban designprojects, such asHorton Plazaand Aranya Nagar, from around the world. The paper concludes withan outlineof future directionsin urban design,including criteria for successful urban designprojects (e.g. striking aesthetics, convenient function andlong-term impact) anda proposedpedagogical approach (e.g. interdisciplinary, in-depth and problem-driven). Provocations In the earlypart of 1998,two provocative urban design eventsoccurred at the Universityof Michigan in Ann Arbor.The rstwas an exhibition organizedas partof aninternationalsymposium on ‘ City,Space 1 Globalization’. The second wasa lecture by the renowned Dutch architectand urbanist, Rem Koolhaas. By themselves,the events generated much interestand discussion, yet were innocu- ous,compared to, say, Prince Charles’s controversialcomments on contempor- arycities in the UKorthe gathering momentumof the New Urbanism movementin the USA.

Architects earn practice by using stakeholder theory and the concept of pro- professional degrees and are licensed, like doctors, lawyers, fessional judgment to describe the activities of architectural and engineers. However, architecture is the lowest paid of practice. Architects are taught the skills necessary to make these four professions. Although buildings are tangible arti- ethical professional judgments in the contexts of design and facts of an architect’s work, the design of a building is less professional service, but they are not necessarily taught easily understood by the lay person than, say, recovery from how to effectively communicate the value of those skills to an illness. Often the public may value the architect’s work those outside the profession. Stakeholder theory provides a based on the subjective evaluation of the observer: they framework to describe the practice of architecture in a way either like it or they don’t. The profession cannot survive on that enables non-practitioners to appreciate value of the the basis of the public’s “like” of their work, as discussed in complex decisions and activities performed by architects. a 2015 article in Forbes magazine, which declared contem- porary architecture to be ugly, irrelevant, and out of touch “There’s a snobbery at work in architecture…The sub- with society.3 In support of this claim, the author offered up ject is too often treated as a fine art, delicately wrapped a description of the American Institute of Architects’ effort in mumbo-jumbo.
